Inadequate Myocardial Oxygen Supply/Demand in Experimental Pulmonary Hypertension
The increased workload of the right heart due to pulmonary hypertension increases oxygen consumption of right ventricular cardiomyocytes because the mitochondria have to operate at a higher rate. Hypertrophy can normalize right ventricular wall stress, thereby also normalizing the rate of oxygen consumption by mitochondria. However, hypertrophy may cause hypoxia in cardiomyocytes because intrac...
متن کاملComparison of acute alterations in left ventricular relaxation and diastolic chamber stiffness induced by hypoxia and ischemia. Role of myocardial oxygen supply-demand imbalance.
To clarify conflicting reports concerning the effects of ischemia on left ventricular chamber stiffness, we compared the effects of hypoxia at constant coronary perfusion with those of global ischemia on left ventricular diastolic chamber stiffness using isolated, perfused rabbit hearts in which the left ventricle was contracting isovolumically. Since chamber volume was held constant, increases...
متن کاملPersistence of regional left ventricular dysfunction after exercise-induced myocardial ischemia.
To determine whether regional myocardial dysfunction occurring after exercise-induced ischemic might be caused by continued abnormalities of myocardial blood flow in the post-exercise period, nine dogs were instrumented with ultrasonic microcrystals for determination of circumferential segment shortening, circumflex artery electromagnetic flow probes, and hydraulic coronary artery occluders. Do...
متن کامل[The imbalance between supply and demand for cardiologists in Spain].
The lack of cardiologists (and of other specialists) is a serious problem that occurs, among other things, because of the poor vision of politicians. Thus, at this point, it would be dangerous to leave them to deal with this issue alone. For this reason, we welcome the fact that the Spanish Society of Cardiology offers this article,1 with respect to which I would like to make a few comments. 1....
متن کاملDemand oxygen delivery during exercise.
Nine hypoxemic patients with COLD, whose hypoxemia is aggravated by minimal exercise, volunteered for this study. Each subject underwent two treadmill exercise trials at two oxygen delivery settings, each on the DODS and SF delivery systems for a total of four exercise trials. We measured SaO2 via ear oximetry and recorded oxygen usage per minute. We compared the oxygen usage required for the t...
